Remove hoses from outside plumbing lines in the winter to prevent frozen pipes. Fix any problems with outdoor plumbing as soon as they appear to prevent bigger problems such as water damage and mold growth.
Homes with municipal sewers benefit from having a professional sewer cleaner come out every two or three years to snake the main sewage line. At a cost of between $75 and $200 as of 2015, snaking out the main sewer removes any tree roots that find their way into the septic system, notes HouseLogic.com.
Add pipe insulation to outdoor pipes and in cold parts of the home. This helps prevent pipes bursting in below-freezing temperatures.
Homes with sump pumps benefit from an annual inspection and cleaning before winter comes. During the inspection, make sure there is no water blocking the end of the drain on the exterior pipe. If the pump has a cleanout cap, remove it and allow the water to exit the pipe.
Homeowners living in colder climates can benefit from installing a freeze-proof spigot outside. This spigot has a long stem that cuts off the water supply closer to the warm house instead of at the faucet itself.
Check the basement behind the outdoor faucet and open it a little to let the water out before freezing temperatures occur. If these pipes freeze, they can burst and cause a flood.
